Below factors must be evaluated when the selection of extruders’ feeding method.

Flexibility

Dry blends segregation

Operational cost and equipment investment cost

Reliability

Automation

Environmental emission

We have two solutions to be selected:

A. Vacuum hopper loaders

more flexible for multiple color and formulation, but higher operation cost and higher investment cost when more extruders to be fed (more than 10).

noise and dust happen sometimes

B. Tube chain conveyors

lower operation cost, no noise and dust happen.

not flexible for multiple colors and formulations

Higher investment cost when less extruders to be fed (less than 10)
